Back in the day [as they say] Local workhouse inmates used to clean our building/shops/offices, etc. And for the most part, they did a good job. If they cleaned our personal work-space , did an extra nice job, we were permitted to buy them lunch, maybe give them a pack of smokes & a soda-pop, etc.
Didn't take them long ..... to figure out that it was a decent way to spend six months to a year,out of their cell for about 6 hours a day 4 days a week, and eat well, at least once p/day.
Well, someone somewhere , started bitchin' about it, unfair labor , etc & so on......So it ended , we hired cleaners/janitors, bought mechanical sweepers & scrubbers, [several thousand dollars], and the shops were never again as clean as they once were.
